History of pregnancy induced hypertension is linked with increased risk of cardio-cerebral vascular events / 中华心血管病杂志

<p><b>OBJECTIVE</b>To compare the incidence of cardio-cerebral vascular events between pregnancy induced hypertension (PIH) women and non-PIH(NPIH) women.</p><p><b>METHODS</b>Ambispective cohort study method was used and 4630 pregnant women giving birth during October 1976 to December 2008 in our hospital and participated the healthy examination between July 2006 and October 2007 at Kailuan medical group were included and divided into PIH group (n = 694) and NPIH group (n = 3936) by the history of PIH. Incidence of cardio-cerebral vascular events (myocardial infarction, cerebral infarction and cerebral hemorrhage) was obtained during follow-up. Multivariable Cox proportional hazards regression models was used to assess the relative risk of cardio-cerebral vascular events.</p><p><b>RESULTS</b>(1) The follow-up time was 2 to 34 (15.32 ± 7.94) years. (2) The childbearing age, systolic blood pressure and diastolic blood pressure before delivery were significantly higher while gestational weeks and weight of newborn were significantly less in PIH group than in NPIH group (all P < 0.01). Levels of systolic blood pressure, diastolic blood pressure, waist circumference, body mass index, triglyceride, total cholesterol and fasting blood glucose during healthy examination between July 2006 and October 2007 were significantly higher in PIH group than in NPIH group (P < 0.05 or P < 0.01). (3) There were 71 cardio-cerebral vascular events during the follow-up. In PIH group, the incidence rate of cardio-cerebral vascular events, myocardial infarction and cerebral infarction was 20.64%, 11.08% and 8.67%, respectively, while the corresponding incidence rate was 7.82%, 4.02% and 2.67% in NPIH group (all P < 0.01). After adjustment for other traditional cardiovascular risk factors, the risk of total cardio-cerebral vascular events, myocardial infarction and cerebral infarction in PIH group was 2.99 fold (95%CI: 1.80 - 4.95), 3.91 fold (95%CI: 1.71 - 8.91) and 3.96 fold (95%CI: 1.95 - 8.05) higher than in NPIH group.</p><p><b>CONCLUSION</b>PIH is an independent risk factor for cardio-cerebral vascular events.</p>

<p><b>OBJECTIVE</b>To evaluate the predictive value of baseline serum high sensitivity C-reactive protein for the first cardio-cerebral vascular event in the population with diabetes.</p><p><b>METHOD</b>In this prospective cohort study, a total of 101 510 employees of Kai Luan Group, who received healthy examination from July 2006 to October 2007, were screened and 7865 subjects with fasting plasma glucose ≥ 7.0 mmol/L or known diabetes mellitus and under insulin or hypoglycemic drugs therapy were followed up for 38 - 53 (48.02 ± 3.14) months.</p><p><b>RESULTS</b>(1) Incidence rates of total cardio-cerebral vascular events, cerebral infarction and myocardial infarction increased in proportion to increased levels of baseline hsCRP (P < 0.01). After adjusting for age, gender, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and cigarette smoking, multivariate Cox's proportional hazards regression analysis indicated that the individuals in the highest quartile of hsCRP levels group (hsCRP ≥ 2.50 mg/L) had an increased risk of total cardio-cerebral vascular events (RR: 1.64, 95% CI: 1.20 - 2.24), cerebral infarction (RR: 1.52, 95% CI: 1.03 - 2.24), myocardial infarction (RR: 2.57, 95% CI: 1.34 - 4.91) compared with those in the lowest quartile group (hsCRP < 0.41 mg/L). (2) Higher baseline hsCRP levels were associated with aging, female gender, higher BMI, SBP, DBP, fasting blood glucose, TC, TG, LDL-C levels and lower HDL-C levels (all P < 0.05).</p><p><b>CONCLUSION</b>Baseline hsCRP level is associated with increased first cardio-cerebral vascular event in the population with diabetes.</p>

Changes of glucocorticoid receptor in hepatic cytoplasm in scalded rats and its regulation by α-MSH and KPV peptide / 第三军医大学学报

Objective　To observe the changes of glucocorticoi d receptor (GR) in hepatic cytoplasm in rats after scalding-induced pathologic al stress and its regulation. Methods　The receptor binding capa city (R0) and the apparent dissociation constant (Kd) of GR in hepatic cytopla sm of normal, low-degree and heavy-degree scalded rats were measured with rad io-ligand binding assay, with ［3H］ dexamethasone as ligand. The changes of R0 and Kd of GR were regulated by injections of anti-rat TNFα, IL-1β a ntibodies, α-melanocyte-stimulating hormone (α-MSH), and KPV peptide( Ac- D-Lys-L-Pro-D-Val) respectively in vivo. Results　The R 0 of GR in hepatic cytoplasm in rats 12 h after heavy-degree scalding ［Mass action robust: （205.52±30.14） fmol/mg; Scatchard: （208.45±30.78） fmol/mg ］were significantly lower than that of control group ［Mass action robust:（307 .86±24.22） fmol/mg;Scatchard:（306.71±27.96） fmol/mg］(P<0.01), but no s ignificant difference was found in the R0 of GR between the control and the ra ts 12 h after low-degree scalding ［Mass action robust: （285.19±16.62） fmol/ mg ; Scatchard: （296.64±16.06） fmol/mg］. The injection of anti-rat TNFα, IL-1β antibodies, α-MSH and KVP all prevented the decline of R0 of GR in h epatic cytoplasm in rats with severe scalding. Conclusion　The injections of anti-rat TNFα, IL-1β antibodies, α-MSH or KPV can attenuate the reduction of GR in rat hepatic cytoplasm caused by severe scalding-induced pathological stress to some extent.
